identifying sourcetypes by index

Builder

Hello,

I'd like to display all sourcetypes available for each index in my environment. Unfortunately, metadata type=sourcetypes doesn't preserve the index name, and I want to be able to run it on the entire set of indexes on whatever instance the search runs on (i.e. I don't want to hardcode index=a OR index=b, etc, into the search). I tried getting fancy:


| rest /services/data/indexes | rex field=id mode=sed "s/.\/(\w+)$/\1/" | search id!="_" | fields id | map search="|metadata type=sourcetypes index=$id$ | stats list(sourcetype) as sourcetype | eval whereFrom=$id$ | table sourcetype whereFrom"

...but the second $id$ is always null. Can anyone give me a good way to list all indexes and the sourcetypes they contain? As a bonus, if you can explain why my map command doesn't work as expected, I'd appreciate it.

earliest=-5m@m latest=@m index=*|dedup sourcetype|table index sourcetype 
  • I always use this to list all sourcetypes and there respective indexes.

That only works if all the sourcetypes have appeared in the past five minutes, though.

You can increase the timerange to one hour and try it. It will just take extra time to give you the result. Will depend on your splunk environment on how much time it will take for search to complete

Understood, but my indexes are huge. I would prefer not to search the data itself if I can avoid it--this is the kind of problem that metadata should solve.

Try this

|metasearch index=* sourcetype=* | stats count by index, sourcetype | fields - count

you will get all sourcetypes faster if you do
| metadata type=sourcetypes index=*

do you have to do this search against "All Time" ? i tried running it and got completely different results when searching ALL Time vs 15 minutes.

This REST search works great, and it is fast, too. I lists all sourcetypes by index and the associated event count:

|rest /services/data/indexes count=0
| dedup title
| fields title
| map  [|metadata type=sourcetypes index="$title$"
        | eval type="$title$"] maxsearches=1000
| stats values(totalCount) AS EventCount values(sourcetype) AS Sourcetype by type
| rename type as index
| fields index Sourcetype EventCount
